Title: Electrical apparatus
IPC: H02J13/00
Filed: 1967-10-18
Abstract: 1,145,679. Signalling over power circuits. ZELLWEGER Ltd. 18 Oct., 1967 [9 Dec., 1966], No. 47432/67. Heading H4R. In a method of signalling over power supply conductors the frequency of the transmitted signal is equal to the sum of a multiple of the mains frequency and a constant low frequency. At the receiver the received signal is demodulated by a frequency which is the same multiple of the mains frequency and applied to a filter of frequency equal to the constant low frequency. The arrangement allows a highly selective filter to be used at the receiver since the frequency deviations in the received frequency will be small due to the low frequency of the constant low frequency signal, which is the only quantity which cannot be exactly synthesized at the receiver. The system is shown in the Figure, in which a frequency multiplier FV derives a frequency, e.g. the 20th harmonic of the mains frequency 50 c.p.s. This frequency is modulated in M by a low frequency, e.g. 23 c.p.s., from which the sum signal, e.g. 1023 c.p.s. is filtered out by 24 and applied via the signalling key 4 to the line 1. At the receiver a relatively broad band pass filter 31 extracts the signalling frequency which is applied to modulator M fed also with the 20th harmonic of the mains frequency from F.V. The difference frequency, e.g. 23 c.p.s. is extracted by a 231 c.p.s. band pass filter 34 and amplified and applied to the evaluation stage 36.

Title: Arc welding
IPC: B23K9/073
Filed: 1968-10-09
Abstract: 1,249,344. Welding by fusion. NATIONAL RESEARCH INSTITUTE FOR METALS, DIRECTOR OF. 9 Oct., 1968 [9 Oct., 1967; 13 April, 1968], No. 47874/68. Heading B3R. [Also in Division G3] In e.g., submerged-arc welding using a consumable electrode 14, the position or depth of penetration of the arc is controlled in response to current changes in a detector member 12 arranged at the desired position or depth of the arc in the joint and which is connected in parallel with a portion of the welding circuit, but in series with the arc. In the embodiment shown the detector member 12, which is connected via ammeter A 2  and series resistor R to the common terminal of the weld power supply 13 whereby it is connected in parallel with the welding circuit, is arranged along the length of the V-groove at the desired depth of penetration of the arc, the connection to the member being at that end towards which the arc progresses during welding. The detector member 12 may be consumable and insulated. The welding current is automatically adjusted to ensure the correct depth of penetration by continuous measurement of the voltage across resistor R, which voltage is fed to the weld power supply 13. Shunt current in that part of the circuit connected to the detector member may arise from its contact with the arc of molten weld metal. The detector member 12 may be of metal the same as the workpieces, or metal such as copper or aluminium; it may be flux-coated. In a second embodiment (Fig. 3A, not shown), a set of detector members (32) in insulant is placed vertically in a parallel-sided joint, each member (32) being connected to an associated shunt circuit, whereby as the members, which extend longitudinally of the joint, are progressively fused vertically, the depth of penetration of the arc is determined and the welding current varied accordingly. In a modification (not shown), two sets of members (32) may be arranged vertically on opposite sides of the weld centre line whereby to detect transverse deviations of the arc and allow correction thereof. In a third embodiment (Fig. 3B, not shown), the width of the penetration bead is detected and controlled using a horizontally disposed set of detector members (32) placed behind a V-joint. Instead of providing an ammeter in the shunt circuit(s), tungstenfilament lamps, neon lamps or other discharge lamps may be used. A transformer may be incorporated to step up the voltage in the shunt circuit. Welding may be performed using a flux-backing.

Abstract: 1,206,140. Zirconiding and hafniding metals. GENERAL ELECTRIC CO. Oct. 27, 1967 [Nov. 10, 1966], No.48886/67. Headings C7B and C7F. A zirconide or hafnide layer is formed on a metal composition, the metal composition having a melting point of more than 800C and at least 50 mole percent of said metal composition being at least one of the metals selected from the class consisting of metals whose atomic numbers are 13, 22-29, 41-47 and 73-79 inclusive, The method of forming the layer comprises (1) providing a fused salt electrolyte, (2) providing an electric cell containing said electrolyte, (3) providing said cell metal composition as the cathode, and joining said cathode through an external electrical circuit to zirconium or hafnium as anode, (4) maintaining said electrolyte at a temperature of at least 800C. but below the melting point of said metal composition and (5) controlling the current flowing in said electric cell so that the current density of the cathode is in the range from 0À01 to 10 amperes/ dm<2> during the formation of the zirconide or hafnide layer; said electrolyte consisting of (a) lithium and/or sodium fluoride, or a mixture of lithium and/or sodium fluoride,with one or more of the fluorides of strontium, barium, magnesium and calcium and (b) from 0À01 - 5 mole percent of zirconium fluoride (when zirconium serves as anode) or 0À01 - 5 mole percent of hafnium fluoride (when hafnium serves as anode) substantially all traces of oxygen and oxides being absent from the electrolyte and from above the electrolyte and an inert atmosphere or vacuum being maintained over the electrolyte at all times; the electrolyte being free from carbon and carbon compounds at least when the said metal composition includes a metal of atomic numbers 23, 24, 41, 42, 73, or 74 during formation of the zirconide and hafnide layers. When the metal composition is Ti, the method may be modified in that no external electrical connection need be provided between the anode and the Ti. The terms "Zirconide" and "hafnide" designate any solid solution or alloy of Zr or Hf and the metal composition whether or not the metal composition forms an intermetallic compound with either metal. Prior to zirconiding or hafniding, impurities such as oxygen and carbon can be removed from the fused electrolyte by an initial electrolysis. Oxygen can also be removed by contacting the fused electrolyte with Zr or Hf. During the "iding" the cell generates electric current. The deposition rate of the Zr or Hf may be increased by impressing a voltage, e.g. to obtain constant current densities during the reaction. The electrolyte may comprise a eutectic mixture of NaF and LiF. The process may be carried out under an atmosphere of Ar, He, Ne, Kr, or Xe. The zirconide and hafnide have hard wear - and corrosion-resistant surfaces.

Title: Fluid amplifiers

Filed: 1971-10-27
Abstract: 1344302 Fluid regulation; fluid-pressure servo-motor systems FLUID DEVICE CORP 27 Oct 1971 [30 Oct 1970] 49972/71 Headings G3H and G3P [Also in Divisions F2 and G1] A liquid level sensing device 20, comprises aligned but spaced emitter and collector tubes 28 and 30 respectively, and a control member 32 which has a lateral opening 32a and into which the emitter tube discharges. With the liquid level lying below the desired level, a substantial proportion of the fluid jet as emitted by tube 28 is collected by tube 30. However, as the liquid level reaches the emitter orifice 32a, the emitted jet spreads out and so a lesser proportion thereof is collected, Fig.3b, (not shown). Thus a signal change takes place in the collector 30 on the liquid level reaching the desired value. Various modifications of the above concept are depicted in Figures 2 to 6, (not shown). In all cases the signal change can be utilized to operate an actuator. In the embodiment of Figure 7, and emitter orifice 82a issues a jet which, when the liquid level is below a predetermined value, passes through the orifice of a fixed plate 84 and impinges upon a vane 86c extending from a collar 86 carried by a valve-operating shaft 86a. As the liquid level rises to such an extent that it interferes with the emitted jet, Figure 7b, the jet becomes deflected in the manner shown whereupon it impinges upon a second vane 86d, such impingement serving to rotate the collar 86 and hence the shaft 86a. Upon the liquid level falling below a value where it interferes with the emitted jet, the system reverts to the state shown in Figure 7, such return being accompanied by a return of the valve to its initial state.
